I have subscriptions to XM (since 2001), Sirius, and Pandora.
... I listen to satellite radio in my cars and at home. I listen to CNBC, CNN, MSNBC, and FOX News, and I will scan 5 or 6 channels to get some interesting music.
... If I hear a piece of music that I like I will use Pandora at home on my Sonos sound system to generate similar pieces of music. For example, if you tell Pandora that you like “Classical Gas” you will get acoustic guitar music that will lead you to musicians like Esteban. Create Esteban Radio on Pandora and you will hear hours of great acoustic guitar music anytime you like. Try it. You simply cannot do this any other way.
I've been a subscriber of XM since the very beginning. I listen to it mainly in my car. I decided to download the Pandora app on my cell phone to hear the difference between that and XM in my car. (I used the SiriusXM app in my car for equal comparison). The music and original content on the SiriusXM app sound WAY better than the music streaming through Pandora. Pandora sounds great on the home computer, but there's no comparison when it comes to sound quality in the car. SiriusXM easily beats Pandora on quality and content.
SIRI's stock price should be at least where Pandora's ended today ($17.41) especially since everyone who listens to SiriusXM is a paid subscriber. SIRI: Cash flow, Content, and Quality + 2.0 by end of year.
